ELECTRIC HEATER.

rSpecification 'of Letters 'PatentI Patented Oct. 9, 191 '7.

Application fried November 14,1916; serial No. 131,2'24.

To all whom it may concern:

lmarked thereon, forming a part of this specification. 1

This invention relates to electric lluid heaters, and has for its object the provision of a device of this character, iii which thehuid may be heated to any desired temperature in a simple and etlicient nianiier. 4

More especially, my invention relates to what are known as elcctrolyticheatei-S, in which the'lluid is vheated directly by the cur4 rent, that is, the fluid forms a `part ofthe electric current.

The present invention consists primarily of a novel device of the character described, comprising a liquid receptacle provided with a bearin at one end, and further provided with an integral seat in the bottom thereof, a support provided with recesses secured upon said seat, electrodes each having one end secured iii said bearing, and the other seated in the recesses of said support, and electrical connections for said electrodes, and furthermore, this invention consists in the various novel arrangements and combination of parts, all of which will be described in detail in the following specification, and then finally embodied in the clauses of the claims.

In the accompanying drawings, in which I have shown a preferred form of my invention,

Figure 1 represents a sectional plan view of a receptacle made in accordance with my invention, taken on lines mof Fig. 2, the cover being removed, and

Fig. 2 represents a side elevation of the saine.

Similar characters of reference refer to like parts throughout the specification and drawings.

In the drawings, l represents a receptacle or container, preferably made of cast aluminium, although porcelain or any other suitable non-corrosive material may be eni- V cyliiidrica in forni, sai

ployed, which4 may be of any shapeor size, according to tieV purpose toy which it is adapted. It may be ornamented in any suitable or desirable inan'ner in case it is intended-for use on the table in the heating of liquids in the preparation of foods or the steiiiliring of instruments. A cover i). ol any convenient'form and provided ivitli u haudlef, preferably of liber, is removably mounted ,upon said receptacle or container 1.- Similarhandles arese'cured to the sides of the'icoiitaiiier;,and the bottom thereof is preferhbly provided with a plurality of fiber feet 4. Y A 4 Vitliiirthe contaiiie'iior receptacle l are ar'raiigedthe electrodes 5-5, between which thellluid isvhto be heated. These electrodes are' preferably similar in 'size and shape, and made of 'soine suitable ludn-corro ible conductor, as graphite or the like. Asshown, said electrodes are supprted on one end in r'ccessesffr'ined in a siiita'bleporcelain or other' 'lion-conducting' bracket 6,V which is upon an integral Seat 8 formed on the inside ..-.,l.5'l-`y: :i

of the receptacle or container 1. The other ends of t-e said electroes are preferably cylindrical ends fitting into metallic sockets 9 from which extend the electrical connections in the formof metallic terminals 10, which may be secured thereto in any convenient or desired manner.

Surrounding and inclosing said metallic sockets 9, are porcelain or other non-conducting bushings 11, which are received into suitable recesses 12 formed in an integral bearing 13 extending into and projecting outward from the receptacle or container 1 near the bottom and one end thereof, as clearly indicated in the drawings.

Suitable apertures are formed in said bearing 13 to receive bushings l-l, through which the terminals 10 pass. The bushings 14 also form a water-tight joint.

The manner ofsupporting said electrodes may, however, be varied in any manner which suggests itself to persons skilled in the art., to meet varying requirements.

In the passage of the current through the resistance offered by the Water, heat is generated and the liquid contained within the receptacle heated very rapidly. When there is no liquid Within the receptacle, there is of course, no action and no burning out of the parts.

Within the receptacle or container l are provided a number of integral supports 15, preferably projecting above the electrodes and upon which may be secured by means of screws, or removably mounted, an instrument tray 16 or the like, said instrument tray in its preferred form, consistino of a'sheet 0f perforated aluminium or other suitable non-corrosive material.

Experience has demonstrated that the or ganization above described is a highly efficient one, and while the device described is the preferred embodiment of m invention7 I do not wish to be limited to tie exact details of construction, combination and arrangement herein shown and described, as obvious modifications thereof, notJ involving the exercise of invention, may be made by any one skilled in the art, and such departures from what is herein shown and described, I consider within the scope and terms of my claims.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is 1. An electric heater comprising a liquid receptacle, provided with a bearing at one end, and further provided with an integral seat in the bottom thereof, a support provided u'ith recesses secured upon said seat, electrodes each having one end secured in said bearing and the other seated in the recesses of said support and electrical connections for said electrodes.

2i An electric heater comprising a receptacle having a bearing at one end, insulating bushings located in said bearing, me-4 tallic bushings secured within said insulat ing bushings, and metallic terminal pins eX- tending from said bushings through the insulating bushings, means located in said bearing surrounding said terminal pins for maintaining a Water-tight joint, a support provided with recesses located within the receptacle, electrodes each having a reduced end, said end being secured in said metallic bushings and the other ends of said electrodes seated in the recesses of said support.

3. Au electric heater comprisingr a liquid receptacle, provided with a bearing at one end, and further provided with an integral seat in the bottom thereof, a support provided with recesses secured upon said seat, electrodes each `having one end secured in said bearin and the other seated intlie recesses of sai support, and electrical connections for said electrodes and a perforated plate removably mounted in said receptacle in close proximity to and above said electrodes.

This specification signed and witnessed this eleventh day of November, 1916,
